To all :1r/wm 'it may concern.' y

Be it known that I, CLARENCE E. MORRI- soN, a citizen of the UnitedStates, residing at Albany, inthe county of Albany and State of NewYork, have invented certain new and useful Improvements in RotaryDuplicating-Machines; and I do hereby declare the following to be Vafull, clear, and exact description of theiinvention, such as `.\\'illenable others skilled in the art to which it may be possible to printvoff a few letters,

if desired, and replace the same with another cylinder for printinganother form of letter.

Heretofore in du'plicatingmachines, strips have been utilized which-areconnected to the ends of the impression roll and, in order to throw thecylinder out of use or to hold the roll away from the cylinder for aninterval' at each revolution, it 4is-necessary to exert an extrapressure upon thestrips, whereas with the reversed, pressure beingrelievednby a cam instead of requiring additional power.

My invention comprises a simple and efficient apparatus of this naturehaving vari`V ous details of construction, combinations and arrangementsof parts which y will be hereinafter fulldescribed, shown in theaccompanying drawings and then specifically del fined in the appendedclaims.

I illustrate my invention in the accom- /meral 15', Vhas mounted 1n saidframe and carries 1n theyv shown clearly inFig. (iof the panyingdrawings, in which:-

perspective of a part of v Reference now being had to the detailsof lthe drawings by numeral, 1 designatesthe frame of the apparatusin whicha shaft 2 is journaled, said shaft carrying two spiderV cylinder heads,designated by numeral 3,A

said heads having each a ange 4, one being shown clearlyv in Fig. 4 ofthe drawings, and 5 designates the circumference of a cylinder which ismade preferably of metal and has its ends 6 turned into rolls and whichengage over the ends of the rib 7 formed upon the edges `of the flanges4, shown clearly in Fig. 3 of the drawings. A wooden` ,strip 8 ismounted in recesses 9 formed in the inner faces of the cylinder headsand being held therein by screws 10 and serving as means for holding thecylinder heads in place. Pins 'I 11 .project from the opposite faces ofsaid 'str1p 8 and over which one end of the impression sheet 12 iscaught. Asheetof fabric 12X, forming a suitable backing for theimpression sheet has loops formed at its ends by turning the latter uponthemselves and stiching the same tothe body of the fabric, an 12 throughsaid loops and serve to hold the sheet of fabric against the outersurface of A bail-shaped member, designated by numeral- 13, has itsangled ends 14 pivotally mounted in apertures in the cylinder heads, andgrooves 15 and 16 are formed the bail may be held in the differentpositions shown in Fi'gs. 3 and 4 of the drawings. `When the bail isadjusted in the position shown in Fig. 3, it is adapted to engage andhold thefree end of the impression sheet 12 upqn the outer surface ofthe sheet of fabric, as shown. y

An oscillating frame, designated by'nuspindle ends 16 pivotally arms 117thereof the spindle ends of'the -roller 18,

and which is adapted to bear frictionally against the impression sheetupon said cylinder. A gear wheel 18 has a hub portion 1 9 journaledfin asuitable bearing in the frame. Aand the. 4teeth of said V gear wheel arein mesh with the teeth of a pinion 20 mounted upon the stub shaft 21upon the frame and. ahandle 22 is fixed to the said designates wireswhich are passedl -in the end of the cylinder head and in which Ashaft21. -Said frame 15 itiwillv be noted, 110

reception of the pin 25 upon which the tilting lever 26` is mountedwhich carries a grooved friction roller 27 adapted to contact with thecam ange 28 of the gear wheel .18. An adjusting screw 29 is mounted inan aperture in the arm 23 and upon the end of said screw the lever32 ispivoted, and a.

suitable spring 35 is interposed between a washer 35X upon said screw 29and the arm 23 and provided sothat, when said screw 29 is turned in onedirection or the other, the tension of the. spring may be increased ordecreased for the purpose of regulating the pressure that it may bedesired to have the impression roller 18 bear against the cylinder. Saidlever 32 has a lug 38 projecting therefrom and adapted to bear againstthe lever 26 to limit thefswinging movement of said lever 32 in onedirection.

Projecting from the under surface of the lever 32 is a lug vhich isconveXed and is adapted to serve asa means for guiding the lever 32.when being swung laterally upon the pin 29, the conveXed edge of the lugL10 coming in contact with the rear edge of the arm 23. Suitable gagesal, regulated by set screws l2, are mounted upon the table 30 againstwhich the paper to be printed upon is adapted to be held.

Projecting from the face of one cyllnder head 3 is a lug, preferably ofV-shapews shown in dotted lines in Fig. 2, and which is adapted to'engage a similar slot. 51 formed on theI face of the cam disk and whichlug and slot are provided for the purpose of causing the cylinder andgear wheel having the cam flange to rotate together and also serving tohold the parts in proper position -so that the a ertures 1n the cylinderheads will register or the purpose of receiving the shaft 2.

ln operation, the 'parts being assembled as shown, one end of theimpression sheet is caught over ythe pins 11 upon one side' of the strip8, passed about the cylinder and its other end held by the bail 13 inthe manner shown in Fig. 3 of the drawings. The paper to be printed uponis placed upon the table and fed frictlonally between the roller 18andthe impression sheet upon the cylinder. 28 comes adjacent to theJfriction roller 27, the pressure will be released from the irnpressionroller 18 and which action would take place after the sheet had beenprinted and, when it is desired to throw the 1mpressioni roller awayvfrom the cylinder when not in use, the, lever 32 is swung laterallywhich will allow the impression roller to drop down out of contact withthe cylinder.

the 4provision of a rotary duplicating lWhen the cam edge of' the diskmachine embodying the features of my invention, it will be noted that asimple and Yeilicient means' is provided whereby the cylinder may beeasily and quickly removed and replacedby others should it be desired todo so and which would be the case where it'is desired to print oil onlya few hundred letters at one time, in which event the cylinder lcould befiled 4away with the stencil tities of letters and, by having differentcyllnders, parts of letters may be, printed in different colors of inkand which will not necessitate the removing of pads and cleaning up ateach time of printing.

What l claim to be new is l. A rotary duplicating machine comprising aframe, a rotatable detachable cylinder mounted -therein and upon whichan impression sheet is adaipted to be held, a

rocking frame, an impression roller carried' thereby and held yieldinglyagainst the surface of the cylinder, a cam disk rotatin with thecylinder, a lever pivotally mounted .omizing in the printing ofuncertain quanp upon the rocking frame, a pulley pivotally mounted uponsaid lever and frictionally engaging the cam disk, a setscrew carried bythe arm of said lever, and a lever pivoted upon the rocking frame andagainst which l said set screw is adapted to bear.

-2. A. rotary duplicating machine comprising a frame, a rotatablecylinder mounted thereon and ladapted to carry an impression sheetthereon, a rocking frame, an impression roll pivotally mounted thereon,an adjusting screw upon the rocking frame, a spring upon said screw forregulating the pressure of the impression, roll against said cylinder, alever pivoted `upon the rocking frame, a grooved pulley carried by saidlever, means for adjusting the latter rela- Y tively to said rockingframe, a cam disk rotating with the cylinder and against which thepulley is adapted to contact, and gear mechanism for rotating thecylinder. ln testimony whereof I hereunto affix my signature in presenceof two witnesses.
